What made you want to do this work?
With a background in business and a passion for digital technologies, I recognized the power of SEO in connecting businesses with their audiences. I wanted to demystify SEO and make it accessible and effective for companies of all sizes. I also wanted to prove that consultants and agencies can be the first growth factor for businesses in general, which I did for my clients.

Many businesses struggle with online visibility and understanding how to effectively reach their target audience. We aim to bridge that gap by providing tailored SEO strategies that deliver measurable results. We try to provide insightful content through different channels, and basically offer an experience of Ethical SEO.

How does your business make money? How does it work?
We offer a range of services, including SEO audits, keyword research, content creation, and link-building strategies.

Q: “How do you measure the success of your SEO strategies?”
A: We focus on key performance indicators such as organic traffic growth, search engine rankings, and conversion rates. So, our phones ringing is one of our KPI! Regular reporting and analysis ensure transparency and continuous improvement.
What is the best part about what you do? What is the worst part?
The best part is seeing our clients’ businesses grow as a result of our strategies. The most challenging aspect is keeping up with the ever-evolving algorithms and best practices in SEO. We receive so many ‘thanks’, it’s really the biggest part of gratification, even before money. Knowing you’ve been helpful is something crucial!
What is your favourite joke about your own profession?
We try to tell a client, “You’re not ranking because your site has no content.” He replied, “But I have a great logo!”
